Remarkably, we highlight striking discordances between mitochondrial and nuclear distributions across their hybrid zones, as well as between their genetic and morphological differentiation. Our study illustrates how genomic-based phylogeographic frameworks can help decipher the high genetic and phenotypic variation of species complexes and substantiate the taxonomic assessment of candidate lineages.

The changes observed may have been caused by release of salamander larvae predatory pressure on invertebrates, which could have promoted their grazing on periphyton, in contrast to their preference for leaf shredding in the presence of salamander. Our study demonstrates an important role of salamander larvae in montane streams through top-down control of lower trophic levels and thus in regulating key stream ecosystem processes.  Leer más.

Visual models indicated that both conspecifics and predators can visually discriminate salamander color morphs under night-light conditions. Assuming the potential role of yellow and red color patches as visual signals, putatively related to social signaling, we could suspect that these colors represent different adaptive optima.  Leer más.

We genotyped 1056 individuals of two anuran and three urodele species (1732–3913 SNPs per species) from populations located in a landscape comprising 64 ponds to characterize fine-scale genetic structure in a comparative framework, and combined these genetic data with information obtained in a previous 2-year capture–mark–recapture (CMR) study.

Critically analyzing PIT tagging methods as well as testing their use in different species is essential to ensure the validity of future research studies and conservation strategies in urodeles. Leer más.
